Code of Federal Regulations (CFR)
The CFR includes rules promulgated by executive departments and agencies of the US government.
The Code of Federal Regulations (CFR) is the codification of the general and permanent rules published in the Federal Register by the executive departments and agencies of the US Federal Government.
The Code is divided into 50 titles that represent broad areas subject to Federal regulation. Each volume of the CFR is updated once each calendar year, on a staggered basis, and is issued on a quarterly basis.
Each title of the Code is divided into chapters, which usually bear the name of the issuing agency. Each chapter is further subdivided into parts that cover specific regulatory areas. Large parts may be subdivided into subparts. All parts are organized in sections, and most citations in the CFR are provided at the section level.
The IHS CFR Publications Collection includes five titles of the Code, including the following:
- Title 14 – Aeronautics and Space
- Title 21 Chapter I – Food and Drug Administration
- Title 29 – Labor
- Title 40 – Protection of Environment
- Title 49 – Transportation
